Abstract

PROBLEM TO BE SOLVED: To provide a tool for passing a string through an object which ensures a string or a rubber string for passing through an object by adapting to a thickness or a shape of the string without damaging the object at which the rubber string or the string can pass through, and further allows strings made of different materials such as a braid and a rubber string to pass together through the object.SOLUTION: In a tool for passing a string through objects, a plurality of loops are formed by twisting a linear-shaped object made of an elastic material so that loop lengths of the loops are gradually shortened from one loop to the next loop and opening widths of the loops are gradually narrowed from one loop to the next loop.

Description

  The present invention relates to a threading tool for passing a string or rubber string through clothing or the like.

  As for the conventional stringer, a threader in which a metal wire is bent to make a strong twist and a string hook is provided at the rear part is commercially available. There is also a threading tool that attaches a piercing body to a holding plate, pierces a rubber string, and stops it with a restraining ring. Patent Document 1 describes a rubber string threading tool in which a round bar-shaped stainless steel, plastic, or the like is folded in two and the end is fixed by welding. Patent Document 2 describes a string threading tool in which a guide portion is provided at the tip of a wire and a slidable fastening body is provided at a loop-like string attachment portion to fasten the tip of a rear end string. Has been. For Patent Document 3, a needle is provided in a string passing hole provided at the rear end portion of the string passing rod, and the tip of the needle is a string passing device with a stopper provided toward the tip end portion of the string passing rod. Are listed.

  Since the conventional stringer has a structure in which a string hooking hole is provided in the rear part of the string threading rod, the string is likely to fall off while being threaded. A threading tool that attaches a piercing body to a holding plate and fastens a rubber string with a stab restraint ring easily damages the string or rubber string. Patent Documents 1 and 2 and 3 are intended to make it difficult for a string to fall off during work. With respect to Patent Document 1, since there is no twist, the force to be sandwiched between rubber strings or the like is weak, and the thickness and shape of the strings and rubber strings cannot be fully accommodated. As for Patent Document 2, when the tightening body and the fixed body move during the operation and the rubber is stretched, it is easy to come off without being tightened. In Patent Document 3, since the needle is oriented in the traveling direction through which the rubber string is passed, the needle is likely to stick into the string insertion hole and is easily pinched, and the rubber and string are likely to fall off. In any of the conventional examples, no measures are taken to prevent the slipping according to the thickness of the string or rubber string. In addition, only one string can be passed. The threading device of the present invention solves the problem of such a conventional configuration, without striking an object through which the string or rubber string is passed through the skirt or pants by the string threading device, Provided is a string threading tool that can securely pass a string without falling off, corresponding to the thickness and shape of the string and the rubber string, and can simultaneously pass a plurality of strings and rubber strings.

  The threading tool of the present invention according to claim 1 is formed by twisting wire rods made of an elastic material to form a plurality of loops, and gradually shortening the loop length of each of the plurality of loops.

    The stringer of the present invention according to claim 2 is formed by twisting wire rods made of an elastic material to form a plurality of loops, and gradually reducing the opening width of each of the plurality of loops.

  In the string threading tool according to claim 1 of the present invention, the plurality of loop lengths formed by twisting the elastic material are gradually shortened from the tip toward the other end. The elastic material is spread and twisted back by the string when the string goes to the other end depending on the shape, so the twisting force to return the elastic material works, and the string does not fall out of the threader during the stringing work . In addition, since there is a continuous twist, the strength for tightening the threading string is great, and the string is held at a position where the loop length differs depending on the shape of the string. Further, when the string is passed, the string always enters a short loop length that is twisted together, so that the string is not pulled out of the threading tool by creating a pushed state. That is, since the string holding portion is provided at a position where the twisting of the loop length differs depending on the thickness and shape of the string, there is an effect that the string does not fall from the threader. Further, the conventional string threading tool is intended to pass a single string, whereas the present invention allows a string of different materials such as a plurality of braids and rubber strings to be simultaneously passed, so that the work efficiency is good.

  In the string threading tool according to claim 2, since the opening width is gradually narrowed from the tip toward the other end even if the twist length is the same, the string is directed toward the other end depending on the thickness and shape of the string. Since the elastic material is spread and twisted back by the string, the string always enters the narrower opening width, so that the string does not come out of the threader while working. There is an effect. That is, the string holding portion is provided at a position where the opening width differs depending on the thickness and shape of the string.

The stringing tool which is the 1st example of the present invention is shown. The string threading tool which is the 2nd example of the present invention is shown. The string threading tool which is the 3rd example of the present invention is shown. The string threading tool which is the 4th example of the present invention is shown. The string threading implement which is the 5th example of the present invention is shown.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a first embodiment, in which a wire 2 made of an elastic material such as stainless steel is folded in two, and both ends thereof are fixed with solder, welding 3 or plastic. Alternatively, the annular wire 2 is used in advance, the loop length is gradually twisted from the tip loop length L1 toward the loop length L6 at the other end, and the relationship between the loop lengths is expressed as L1>L2>.L3>L4>L5> L6. To pass the string 5 of the string threading tool 1, the string tip is passed through the largest loop length 4, and the string 5 is pulled toward the other end at a right angle to the threading tool. The string 5 is locked at different positions of the loop length. When the stringing is finished and the string 5 is removed from the stringer 1, the string 5 is removed by pulling it toward the tip.

  FIG. 2 shows a second embodiment in which the loop lengths of the stringer 1 are substantially the same, and L1≈L2≈L3≈L4≈L5≈L6. The opening width in the direction orthogonal to the longitudinal direction of the stringer is gradually narrowed from the tip toward the other end to form the stringer 1 that satisfies A1> A2> A3> A4> A5> A6.

  FIG. 3 shows a third embodiment, in which the loop length is gradually decreased toward the left and right with the largest loop length 4 of the stringer 1 as the center. L6> L5> L4> L3> L2> L1 The stringer 1 that satisfies <L2 <L3 <L4 <L5 <L6 is formed.

  FIG. 4 shows a fourth embodiment in which the largest loop length 4A, 4B is set on both sides and the loop length is gradually decreased toward the center. L1> L2> L3> L4> L5> L6 <L5 <L4 < The stringer 1 with L3 <L2 <L1 is formed. When moving to the next operation during the stringing work, the work efficiency is good without paying attention to the direction of the traveling direction because of the same left and right shape.

  FIG. 5 shows a fifth embodiment, in which the largest loop 4A, 4B is formed on both sides and the loop 4C is formed at the center. L1> L2> L3> L4> L5> L6 <L5 <L4 <L3 <L1> L2> L3> L4> L5> L6 <L5 <L4 <L3 <Increase the loop length gradually from the loop length on both sides toward the center and gradually increase from the minimum loop length toward the center. The stringer 1 is formed such that L2 <L1> L2> L3> L4> L5> L6 <L5 <L4 <L3 <L2 <L1. The string threading tool 1 can simultaneously pass a plurality of braids 5 and a string of different materials such as a rubber string 6. In the string threading tool 1 of the present invention, since the string 5 moves from the larger loop length and opening width to the smaller one, the string 5 is positioned at a position where the loop length and opening width differ depending on the thickness and shape of the string 5. Is held, and there is an effect that the string 5 does not fall out of the threader 1 because there is a continuous twist. While the conventional string threading tool 1 is intended to pass a single string 5, the present invention can simultaneously pass a plurality of braids 5, rubber strings 6, etc.
